This is the computer I have, does this ram support this computer? http://www.amazon.com/Optiplex-755-3-...

Unfortunately not in the slightest. This memory woudln't physically fit into the sockets for the 755. You would need Non-ECC Unbuffered parts, we have 2x2GB as ASIN: B00D6Q2KNA

Yes this does support DDR3 1066 MHz ram, but I would recommend this: Kingston Technology HyperX 8 GB (2x4 GB Modules) 1600 MHz DDR3 Dual Channel Kit (PC3 12800) 240-Pin SDRAM KHX1600C9D3K2/8GX

those memories ram not work with your computer, all you need are: 1GB DDR400 PC3200 128x64-400MHz, 184p DIMM, 2.5v, Sync, CL = 3.0

It seems Dell uses the same model numbers for different computers over the years, I found this http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf which is for an older version that would for sure not work with the ram. Or I guess looking at your link no it won't work, this is DDR3 memory, where as yours uses DDR2.But you could try downloading CPU-Z (http://www.cpuid.com/softwares/cpu-z.html), go to the SPD tab after memory, you can at least get what speed of ram you have there and work off that.

this Ram is DDR3, as long your motherboard supports DDR3 modules ,your be fine. However, if your motherboard is only support DDR or DDR2 then this one will not fit. my advice is check the specs of your motherboard first. hope this helps you...

Yes, as long as you have Intel Xeon processor this ram will work fine. Mine has been working great since I installed it almost a year ago. It was the best price for RAM i could find.

It should be fine. I bought an Dell 745 Optiplex and I had no problem with any of my older items. Hooked up and running with no problems.

yes, just make sure to check the compatibility list for your ram, the booklet included is outdated.

I don't know. Try a site like crucial.com lets you search for RAM based on your computer model.

I believe so.The RAM doesn't have high profile heatsinks on it so I think you'd be ok.That being said, it might be worth checking the motherboard vendor's QVL list which will tell you what memory kits were tested and working with your motherboard.You can still use ones not listed on the list, but it may give you some perspective as to what to look for.

This should work in your motherboard. It is essenyially the same as the other RAM you mentioned

Please go to Crucial.com and install their tool. They will tell you what ram to use. It is a free utility, and does a wonderful and correct job. It has never given me the incorrect information. This is where everyone should start to select the correct ram. All I did, was gave a critical review of the ram I installed, at the recommendation of this utility. You can't go wrong.

Your ram appears to be desktop ddr3, so it should work in this board. I am running 4 8gb dims. The CPU appears to be LGA 1155, so it should work as well. Gigabyte site should have lists of compatible cpu's and memory. I assume your concern is avoiding purchase of a new cpu for a better mobo. I am not thrilled with this mobo, and if you can find a compatible alternative (ASUS,MSI,EVGA?), it might we worth the effort.

The Dell Optiplex 780 can ONLY take DDR3 RAM, if you see DDR2 then that was a mistake by another seller. If you have any questions please call us 844-889-1070 and we will be happy to help you and ensure you get the computer you want. We are RE-CIRCUIT. Thank you.

Should work as Akshay said. But to be sure download the free system scanner from crucial.com, that's what I did and just copied and pasted the ram type and compared prices here on amazon.

It looks like the Optiplex 745 motherboard uses DDR2 ram, the likes of which DDR3 is not compatible. So no, this ram will not work in your computer, you need DDR2 ram.

Yes your machine needs DDR2 Memory, I just installed this memory in a 745 / 3.4 Dell Optiplex 745 for a friend. You need to run Win XP/7 - 64 Bit to use more than 4 Ghz of Ram, Your machine should run 8Ghz with Windows XP/ 7 - 64 bit but only 4 with Win 32 bitMemory Type: DDR2 PC2-6400, DDR2 PC2-8500, DDR2 PC2-5300, DDR2 (non-ECC)Maximum Memory: 8GBSlots: 4
